VENTILATING ATTACHMENT FOR TANKS. u

SPECIFICATION forming part of Letters Patent No. 749,802, dated January19,` 1904.

Application filed September 15, 1902. Serial No. 123,441. (No model.)

To all wiz/0711, it 77H07/ concern:

Be it known that I, CHARLES NOLLER, acitizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented a new and useful Ventilating Attachment for Tanks, of which thefollowing is a specification.

MyV invention relates to automatic air-regulators for beer-tanks. I

The object of my invention is to provide an automatic air-regulatingdevice for beer-tanks invention consists of an air-receiver providedwith two-detachable heads with openings therein controlled by valveshinged to said detachable heads, one of which is employed to permit theescape of air or gas from the tank and the other to permit the suctionof air into the tank. n A short tube `vertically projecting from theunder side of the air-receiver is provided at the end with a iiangebase,which adapts it to be fastened to a tank by means of screws or said endto be screwthreaded on the outside, permitting it to b e attached to atank by screwing it into an opening therein. lIn the top of theair-receiver a gage and sight-opening is provided for the purpose ofpermitting the contents in a tank to be gaged through the saidair-regulating device.

In order to enablelothers skilled in the art to which my invention mostnearly appertains to make and use the same, I will now proceed todescribe its construction and operation, reference being had to-theaccompanying drawings, forming a part of this specification.

Figure 1 represents an end view of my device. Fig. 2 represents asectional view of Fig. 1, taken on dotted line 2 2, Fig. l, looking froma point toward the left in the direc- C is a detachable head providedwith a'n airy outlet opening E and is inserted and held in the end ofone of the tube extensions B by means of a screw-thread whichis provided0n a portion of the periphery thereof and engaging a correspondingscrew-threaded portion of the interior walls of the said tube extension.F is a valve employed to control the opening and closing of saidair-outlet opening E and is attached on the outside to said head C bymeans of a pin H inserted through a hole in the tongue extensions S ofsaid valve F and supported in the lugs Gr on the upper outside portionofsaid head C. l

I indicates a valve employed to control the opening and .closing of theair-inlet opening E in detachable head D and is attached to the insideofsaid head D in the same manner as valve F, the head D being inserted andheld in the tube extension B in the same manner and by similar means ashead C.

J indicates a short vertical tube extension from the under side of theair-receiver A, being integral therewith, and is provided with aHarige-base K, adapting it to be fastened to a tank O by means of screwsQ, inserted through holes R in said base K and secured into said tank,or the end of said tube J may be provided with screw-thread L on theoutside thereof, which adapts it to be attached to tanks by insertingthe same in a screw-threaded opening in said tank, in which case theiange-base K may be dispensed with.

' M indicates a detachable screw-cap employed to closea sight and gageopening in the top of the air-receiver A and is provided with awrench-seat N thereon.

TOO

and air-outlet openings E, as shown in Figs.

l and 2. r[The valve-seats of the air-inlet and air-outlet openings inheads C and D are slightly obtuse and on an angle, as shown in Figs. 1and 2, which permits of close contact of thc hinged valves F and I inclosing said openings through the gravity of their own weight exceptwhen the same are overcome by the suction and escape of air into andfrom the tank.

The operation of my device may be eX- plained as follows: /Vhen liquidis turned into the tank O through the faucet P by means of ahose-coupling or feed-pipe connected therewith, (not herein shown,) theair thereby accumulating in the tank rises up into the airreceiver A,closes the valve l in the head D, and opens the valve F in head C,passes out, and escapes through the air-outlet opening E therein. Gasaccumulating from liquid undergoing' or passing' through the stage offermentation in the tank, such as beer or other malt liquors, operatesthe valve F and escapes from the tank in the same manner as air, aspreviously described. Then liquid is drawn from the tankthrough thefaucet P or other means connected with said tank, the suction causedthereby in the air-receiver closes valve F in head C and opens valve Iin head D, permitting air to be( drawn into the tank through theair-inletfopening E in said plug l), and thereby facilitating the flowof liquid through' the faucet P or other means of drawing same.

The air-inlet opening in head D may be smaller in size than theair-'outlet opening in head C, as shown in Fig. 2, which permits andregulates a requisite supply or current of air to be drawn therethroughinto the tank by suction when liquid is being drawn therefrom.

By making the heads C and Ddetachable renders the interior of theair-receiver A to be easily and conveniently cleaned of any forma- Itionthat may be deposited therein from vapor arising from liquid in thetank.

With my device the liquid in the tank is always kept intact, and alltendency of dust, dirt, and undesirable foreign mattei' collectingtherein is obviated.

Having thus described my invention, what 1 claim as new, and desire tosecure by Letters Patent, is-

1. The combination in ventilating attachment for tanks, of anair-receiver provided with a sight and gage opening, the detachableheads having an opening therein, and valves controlling the sameattached thereto, sulstantially as described and for the purposes setforth.

2. In ventilating attachment for tanks, the combination with the air-receiver, the detachably-attached head provided with an airinletopening and the detachably-attached head provided with an air-outletopening therein, valves attached to said heads, the sight and gageopening in said air-receiver, means for attaching said Ventilatingattachment to tanks, all connected and operated, substantially asdescribed and for the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

CHARLES NOLLER.
